Automobile Shredder Residue (ASR) is the industrial waste generated after the processing of end-of-vehicles. Urethane foam, polypropylene and ABS resin are plastics mainly in light ASR. In this study the experiments on the liquefaction of these plastics were carried out using potable reactor (vessel volume : 120 ml). 49.75 g of organic solvent (engine oil) and 0.25 g of plastics samples were mixed in the vessel at the agitator rotation of 600 rpm. Then all of urethane foam and polypropylene were melted at the temperature of 250 degrees for 10 minutes although most of ABS resin was not melted at the temperature of 300 degrees for 10 minutes.
